Produce high-frequency high-tension electricity through positive and negative two leads output when high frequency electric source gets after electric, positive electrical is exported to molybdenum filament net 22 and is anodal current potential, and negative electricity is exported to water curtain net grid 29 and made its electronegative position.Owing to keep certain arcing distance between water curtain net grid 29 and the molybdenum filament net 22, this moment is under the effect of high voltage electric field, molybdenum filament net 22 positive poles are to the negative discharge formation streamer breakdown water curtain net grid 29 of water curtain net grid 29 and the air between the molybdenum filament net 22, with oxygen molecule (O
2) smash into antozone (O), because antozone (O) is extremely unstable, instant and oxygen (O
2) carry out combination and form active oxygen (O
3) (being commonly referred to as ozone); The hydrone that soaks at water curtain net grid 29 was crashed to pieces and formed hydrogen and oxygen (H under the effect of high voltage electric field this moment
2+ O
2), while oxygen molecule (O
2) be crashed to pieces into antozone (O) again, antozone (O) again with oxygen (O
2) carry out combination and form active oxygen (O
3), this active oxygen has stronger sterilizing ability.Active oxygen (O
3) when passing water curtain electrode and water curtain net grid, be absorbed and form active oxygen dissolving water, can carry out oxidation Decomposition, sterilization etc. to pollutant, make the air that passes water curtain net grid 29 carry out disinfection, purify, the air of cleaning is along with the driving of shaft type impeller of blower is transported to indoor, give indoor a large amount of oxygen that increased, improved the output of active oxygen simultaneously again.
Seizing the pollutant such as pathogenic bacteria, dust of air in the recirculation water in flowing to lower header S on both sides by the arms, in lower header, concentrating and handle once more.The active oxygen that exists in the lower header S is by O
3Generator 85 constantly replenishes and to provide.O
3Generator 85 is fixed in the housing 2, O
3One end of generator 85 is connected with air intake pump 78, O
3Generator 84 also is connected with the power supply of high frequency electric source controller 89.At O
3Be provided with positive and negative high-field electrode in the generator, under the effect of high-frequency and high-voltage 400V-5KV, its inner air of ionization makes it generate active oxygen O
3Come.(relevant O
3Structure this paper of generator no longer describes).O
3Generator 85 is connected to active oxygen disperser 62 in the lower header S by appendix 77.Active oxygen disperser 62 disperses support 61 to be fixed on the bottom of lower header S by active oxygen, and active oxygen disperses the outer setting active oxygen secondary disperser 65 of support 61, and active oxygen secondary disperser 65 is provided with active oxygen secondary dispersion hole 64.Active oxygen disperser 62 is constantly carried active oxygen (O by active oxygen secondary dispersion hole 64 in the water in lower header
3) form active oxygen dissolving water and carry out secondary sterilization, purification.
S is provided with immersible pump 48 in lower header, and the outlet of immersible pump 48 is provided with upper hose 41, and upper hose 41 is connected to upper water box base plate water inlet.Immersible pump 48 is evacuated to upper water box 8 with the water of lower header 42 through upper hose (41) and carries out the recirculation water circulation, can utilize the certain water level of upper water box water inlet 18 continuous supplementing water maintenances simultaneously.Here it is pointed out that in lower header S to be provided with dividing plate (accompanying drawing does not show) between the active oxygen disperser 65 and immersible pump 48, make the active oxygen O in the water
3Can not be siphoned away by immersible pump 48.
Pollutant in lower header S constantly are deposited on the bottom, and it has influence on the turbidity of lower header internal reflux water, is provided with the turbidity checkout gear at lower header S.The turbidity of water is by the both sides at the bottom of case a pair of turbidity transducer 53 to be installed to realize.Be installed on the turbidity transducer support 50 by turbidity transducer clamp nut 51 at turbidity transducer 53, support is fixed on the base plate of lower header 42 by pick off hold-down bolt 56, the outer setting of turbidity transducer 53 has waterproof case 52, the infrared emission tube that is provided with in its shell connects by the signal terminal 72 of turbidity transducer, infrared receiver tube connects by turbidity transducer sensor-lodging terminals 73, has waterproof to fill glue 54 between them and seals.When water was in normal condition, pollutant were less to ultrared absorption, and the sewage draining valve that the lower header bottom is provided with is positioned at closed condition; When the water of lower header pollutes seriously, a little less than must causing the infrared ray emissive porwer of transmitting tube to fall, and the intensity that receiving tube obtains obviously reduces or can not get signal, central controller was judged back output one control signal and was sent alarm signal this moment, reminds people is opened sewage draining valve, discharges water pollutant.
In upper water box 8, be provided with condensate tank of dehumidifier, include high water level sensing G1, be used to measure the high water level in the water tank; Low water level sensor G2 is used to measure the low water level in the water tank, and the common electrode G of level sensor is arranged.When the water level in the upper water box 8 was lower than low water level sensor G1, the normal potential electrode did not have signal of telecommunication output, and after the CPU detection by central controller, upset is exported to high level water-retention electromagnetic valve and opened, and starts immersible pump 48 and carries out water filling; When water level touches high water level sensor G2 lower surface, this signal passes to the CPU input by pilot and judges that back upset output low level water-retention closed electromagnetic valve immersible pump 48 stops to supply water, and the cue of sensed water level is presented on the display screen of central controller.Lower header is provided with condensate tank of dehumidifier equally, and operating principle is no longer described.
